I'm currently having issues with the broadcom-sta-dkms drivers on my Macbook. I used Keryx to download all the packages and their dependencies on another computer, and installed them using "dpkg -i *.deb" while in the correct directory. I then followed the instructions here to try and connect to my home wifi, but the iwconfig command returned with "no wireless connections". I'm not really sure where to move forward from here, because the solutions I found on Google were all for slightly different issues.
